DO meters for laboratories

DO meterEdaphic Scientific supplies dissolved oxygen (DO) meters for laboratory benchtops across a range of applications including scientific research, aquaculture, water quality, wastewater, laboratories and more. Benefits of our dissolved oxygen (DO) meters include:

  • Extended DO range up to 90 ppm (mg/L) and 600%
  • Measures DO, atmospheric pressure and temperature
  • DO direct, DO direct/autohold, BOD: Biological Oxygen Demand, OUR: Oxygen Uptake Rate, SOUR: Specific Oxygen Uptake Rate
  • Temperature and atmospheric pressure automatic compensation
  • Automatic or Manual salinity compensation
  • Fully customizable
  • In-built data logger: large log memory using different logging methods
  • Polarographic probe with built-in temperature sensor


available models
  • HI-INT – Portable or Benchtop pH Meter with interchangeable sensors (additional sensors include EC, DO and ISE). Product Link Page.
  • HI-MULTI – 3-in-1 Portable or Benchtop Meter to measure pH, EC and DO simultaneously. Product Link Page.
